Recognizing domain redirection

Question

Hello!

I have two domain for my site. The main site is example.net, and I have example.com.

If someone type example.com (or www.example.com, http://example.com or whatever) then I redirect them to example.net (my provider set domain redirecting).

So, is it possible, to take into a php variable if someone come from .com or directly type .net?

Thank you

Answer 1

why don't use just redirect them to .net?from=com ?

Answer 2

If the host is doing the redirecting and you don't have control over it, then it might be worth looking at $_SERVER['HTTP_REFERER'] depending on how they are doing the redirect. Note that this is header not guaranteed to be there and can be spoofed by the client.
